Uncertainty in the working environment of the hot storage battery groupThe power supply of the UPS power supply system is closely related to the ambient temperature. In general, the performance parameters of the battery are calibrated at room temperature to be 20 ¡ã C, and when the temperature is below 20 ¡ã C, the battery is available The capacity of use will be reduced, while the capacity of the temperature is increased, which is slightly increased.

The advent of the information age, let the public have reached an unprecedented height on the dependence of information technology. Let the information leave the electricity, leaving the energy carrier, and its endless power will stop, and the UPS is safe to ensure the safety of information. Although it is the “protective god” of IT equipment, it is sometimes very fragile. If you use improper or other reasons, the damaged chance is very large, especially in cool summer, accounting for about 50% of the whole machine – battery It is more susceptible to damage. Once the battery has failed, it is generally replaced.

The power supply of the UPS power supply system is closely related to the ambient temperature. In general, the performance parameters of the battery are calibrated at room temperature to be 20 ¡ã C, and when the temperature is below 20 ¡ã C, the battery is available The capacity of use will be reduced, while the capacity of the temperature is increased, which is slightly increased. Different models of different models are different from the degree of temperature. According to statistics, at -20 ¡ã C, the battery can only reach around 60% of the nominal capacity. The impact of visible temperatures cannot be ignored. Although the operating temperature allowed by the battery is -15 ~ + 45 ¡ã C, the optimum operating temperature of the battery should be 25 ¡ã C.
Be
In addition, when the ambient temperature rises, the “storage life” inherent in the battery itself gradually shortened. As the summer is coming, the temperature of the battery is continuously increased, and the discharge capacity of the battery will also increase, but the ambient temperature exceeds 25 ¡ã C, as long as the temperature is 10 ¡ã C per liter, the battery life will be reduced, so, Try to ensure that the work environment of the battery can be operated in the range of 10 ¡ã C to 25, and it is usually not over 15 ¡ã C to 30 ¡ã C. When the temperature is too low, the nominal delay will not be reached.
Be
In general, the battery pack and the UPS unit are typically placed together, so the temperature of the UPS distribution chamber is generally maintained between 10 ¡ã C to 25 ¡ã C. As we all know, the user will arrange the battery pack to charge the time of charging in the Spring and Autumn Season, which should be more cool for these time, and it is beneficial to the battery equilibrium. However, cool summer usually makes the indoor temperature exceeds 25 ¡ã C, which requires refrigeration measures to keep the room temperature at 25 ¡ã C, which not only guarantees the life of the battery, which is also advantageous to charge the balance of the battery.
Be
Therefore, before summer arrival, according to the current situation, the current situation may be predicted to predict the possible temperature of the UPS donor, consider whether air conditioning or add refrigeration equipment in the computer room power chart to ensure that the battery pack and the UPS unit work in summer. The environment guarantees the reliability of power s
